Done. I went through Karl Rehn's Defensive Pistol Skills 3 course. The gun ran flawlessly using my 124-grain FMJ handloads. The DA trigger has smoothed up to the point where it's almost revolver-like and my only mod has been to install a 12 lb. hammer spring. The only issues I had were due to excessive operator headspace. I used a JMCK OWB2 and it also performed excellently. I have a new carry gun. Now I just need to sell some stuff to finance a backup.I've got a class next Saturday that I'd like to use for final vetting to make this my new carry gun.
